SPOOL.

Application filed November 5, 1923. Serial No. 672,697.

and may be economically produced.

Further objects of my invention are to permit the use of a spool supporting and driving mandrel in the spooling machines-,-

to eliminate the necessity for peripherally grooving one of the spool heads to receive a driving belt, to provide a simple driving connection between the mandrel and spool, and in general to provide an improved spool construction.

I The many other objects and advantages of my invention will be better understood by reference to the following specification when considered in connection with the accompanying drawing illustrating a selected embodiment thereof, in which Fig. 1 is a central longitudinal section of a spool embodying the principles of my invention.

Fig. 2 is a detail sectional view of a partially completed spool, illustrating one method of constructing the same,

Fig. 3 is an end elevation of the spool as shown in Fig. 2.

Fig. 4 is side elevation, partially in section, of the spool mounted upon a mandrel in a spooling machine, and

Fig. 5 is a detail sectional view, illustrating another method of constructing the spool.

Referring to the drawing, the spool comprises a tubular body 5 provided with integral end flanges or heads 6. A bushing 7 having a peripheral flange 8 formed on one end thereof, is secured in each end of the body with the outer end of this bushingpreferably flush with the corresponding endface of the body. This flange 8 fits-within the slightly enlarged outer end of the bore and abust the shoulder 9. An annular lip 10 on the end of the body is spun or pressed over the beveled outer edge 11 of the flange 8 to permanently retain the bushing in position.

The spool is adapted to be mounted on a supporting and driving mandrel 12 and each of the flanges 8 is provided with a perforation 13 to admit a pin or key 14 on such mandrel to form the driving connection be tween the mandrel and the spool. By thus providing a perforation in each end, the spool may be placed upon the mandrel with either toward the driving pulley 15 thereof.

I prefer to form the body of the spool of aluminum alloy, bakelite, or other material which may be readily cast, molded or otherwise formed in the desired shape and which combines lightness with durability and strength. The bushing is preferably made of pressed steel. In the embodiment illustrated in Fig. 2, the body is formed of aluminum alloy cast in the shape there indicated. The bushings are then inserted in their respective ends and the lips spun or pressed over to form interlocking joints, as indicated in Fig. 1. This method of mounting the bushings within the body of the spool has been found to be advantageous, as itinsures the bushings being securely fastened in place and provides a spool which is neat and attractive in appearance. 1

In Fig. 5 is illustrated a difl'erent method of forming one end of my improved spool, The steel bushing 25 in this end is placed in the mold and cast or molded in the body 26 of the spool. The bushing is retained in the body by the overlying lip 27 as before, but the pressing or spinning of the lip is eliminated. The opposite end of this spool would be formed in the manner previously described.

The spool is placed upon the mandrel 12 by inserting the spindle 16 through the bushings of the spool, rotating the spool upon the spindle to bring the pin 14 into registration with the corresponding perforation 13 in the spool, and then sliding the spool into contact with the pulley 15, as indicated in Fig. 4. The spool is held in this position by a nut 17 on the threaded end 18 of the spindle 16. The mandrel is then placed between the usual supporting centers 19 in the manner indicated. The pulley 15 of the .mandrel is provided with a peripheral the head of the spool to receive a driving belt and materially reduces the cost of pro-' vention, and I reserve the right to make all such changes therein as fairly fall Within the scope of the following claims.

I claim as my invention:

1. 'In a spool, the combination of a cast metal body comprising a barrel of relatively large internal diameter and having integral outwardly projecting end flanges, said barrel being counterbored in one end to form a recessed seat in said end, a bushing for the end of said body comprising a metal disk fitting and secured in said counterbore and provided with a central aperture of relatively small diameter, the outer margin of said disk being supported by said seat.

2.. A spool comprising a moulded tubular body of relatively large internal diameter and a bushing having a central bore of relatively small diameter secured in the end portion of said body and retained therein by the conformation of said body.

3. Ina spool, the combination of a cast metal body comprising a barrelof relatively large internal diameter and having integral outwardly projecting end flanges, said barrel being counterbored in one end to form a recessed seat in said end, a bushing for the end of said body comprising a metal disk fitting and secured in said counterbore and provided with a central aperture of rela tively small diameter, the outer margin of said disk being supported in said seat, and a portion of the metal of the body being swaged over the outer edge of said disktto lock same in said counterbore.

4. A spool comprising a tubular body of relatively large internal diameter having a counterbored recess in the end thereof, and a tubular bushing having a central bore of relatively small diameter seated in said recess, material of said body at the side Wall of said recess being upset to co-act with the periphery of 'sald bushing, for locking the latter in place.

5. A spool comprising a moulded tubular body, a seat on one end of said body, an annular lip surrounding said seat and a bushing seated on said seat and retained thereon by said lip.

6. A spool comprising a molded tubular body having the endportions of the bore enlarged and an annular lip on each end surrounding said bore, and pressed metal bushings inserted in the opposite ends of said bore, each of said bushings being provided with a peripheral fiangeiat its outer end fitting the corresponding enlarged portion of the bore and being retained therein against the shoulder formed by such enlargement by the adjoining lip.

7 In a spool, the combination of a cast metal body comprising a barrel of relatively large internal diameter and having integral outwardly projecting end flanges, said barrel being counterbored in one end to form a recessed seat in said end, a bushing for the end of said body comprising a metal disk fitting and secured in said counterbore and provided with a central aperture of relatively smalldiameter, and an annular flange surrounding said aperture, the outer margin of said disk being supported by said seat. 4 8. In a spool, the combination of a cast metal body comprising a barrel of relatively large internal diameter and having integral outwardly projecting end flanges, said barrel being counterbored in one end to form a recwsed seat in said end, a bushing for the end of said body comprising a metal disk
